Maybe some useful info here? http://www.distant.ca/UselessFacts/fact.asp?ID=215African Gambian Pouch rats, also known as the African giant pouch rat are the largest rats in the world. They grow to 13-17 inches from tip of nose to the base of the tail and the tail is about the same length or longer. They can be more than six pounds. They live in forests and thickets in from Senegal to Central Sudan and down to South Africa.

A giant African rat has become man's second best friend as it joins forces with the dog to sniff out landmines in Mozambique.

The Belgian de-mining research group APOPO has eight of the rodents working alongside dogs and metal detectors on a minefield in Mozambique's coastal town of Vilanculos, some 650 kilometres north-east of the capital Maputo.

The Apopo site is interesting; no mention of TAR I could find, but all the rat videos, rat pictures, Hero the rat mascot, and rat news you could want. Even with the flack jackets, I can't believe the producers would expose the racers to any real danger. Maybe it's an "amazing" minefield.

I only see one member of each team wearing the body armor, and the card Mirna is holding looks red, so maybe a Roadblock. Some info on the search string from the Apopo site:

Quote

The rat is guided by a search string, which is connected between its two trainers. The rat moves systematically up and down the search string, processing lane by lane through the suspected box. Both trainers take position at opposite sides of the box in the safe lane, fixing the search string to the lower leg. When a rat reaches the end of the box, the operators make a lateral step, and the rat moves into the next lane. A box or lane system provides the safe access lanes for the trainers. APOPO is using 5 by 20 meter boxes, which means that the rat has to search 40 lanes of half a meter to clear one box.

ROADBLOCK sure looks like the Rat Race. We see Charla, Ian, Eric, Kandice (?) wearing the protective clothing and Danny, Joyce, a BQ all watching together. Danny has Roadblock red banner clue in his hand. Also looks like many of the teams are doing the task together.'Also looks like a little sliding on a glacier in Argentina before departing for Africa.

RACERS DEPART ARGENTINA AND HEAD TO MOZAMBIQUE WHERE ONE TEAMíS TAUNTING OF ANOTHER TEAM QUICKLY ESCALATES INTO A WAR OF WORDS, ON "THE AMAZING RACE: ALL-STARS" SUNDAY, MARCH 18, 8:00-9:00 PM ET/PT

"You Need To Watch Your Jokes, Guy" - - During a Roadblock, Teams must get up close and personal with a rat in order to receive their next clue, on THE AMAZING RACE: ALL-STARS, Sunday, March 18, (8:00-9:00 PM, ET/PT) on the CBS Television Network.

We just saw glacier scenes in the preview of Episode 5. Episode 4 contained an unexpected 16 hour rest stop. I believe that the 36 hour rest stop we had predicted is now out the window. The most logical place for glaciers is in the Chilean portion of Tierra del Fuego National Park, which they are close to while staying on Isla Redonda in the Argentinian portion of that park. I predict that the glacier scenes will take up the entire following day (Nov. 27) and that somehow Joe and Bill get behind the rest enough to miss the Nov. 28 morning flight to Buenos Aires, which as I have pointed our before does not cost them anything.
